Application tiled July 6,

l This invention relates to manifoldlsheets.

' Objects of this invention are to provider manifold sheets of novel construction which provide means for turning the pages with the point of the pencil or other instrument and for turning a carbon sheet into or out of, position by means of the pencil without requiring the operator to handle either the sheets or more particularly the carbon with his hands.

In greater detail, an object 'of this invention is to provide manifold` sheets so conl'struc-ted that the sheets on opposite sides of vthe carbon and the carbon enclosed between the sheets are each provided with notches or' lcutouts which are out of register.

in the accompanying drawings, in whichz Figure 1 is a view of the manifold sheets with parts broken away to show the interior construction.

Figure 2 shows the book to a smaller scale with` two leaves, normally superimposed over the carbon sheet, turned outwardly.

Figure 3 shows the book in a further stage of manipulation. y

The book comprises a base 1 to which are attached a pluralityof sets of leaves consisting of an upper leaf 2, an intermediate transparent or tissue paper leaf 3, and a bottom leaf 4. .I

It is to be noted that the leaves 2 and 3 have their lower right hand corners cut away, asv indicated at 5, to permit the introduction of the point of a pencil without engaging the carbon sheet or any other'sheet in the book. The carbon sheet 6 is provided with a notch or cutout7 preferably along its lower edge.

lFrom a reference to Figure 1, it will be seen that the notch 7 is enclosed by the notch 5 although this identical construction need not necessarily be followed. It is, how? ever, to be noted that the notches 5 and 7 permit the successive use thereof without danger of simultaneously engaging the two sheets 2 and 3 and the carbon sheet.

If desired, the carbon sheet may be permanently attached to the base 1 or, if preferred, both the set of leaves and the carbon sheet may be detachably related. For ex- 1925. Serial N0. 41,841.

ample, the main base 1 may be provided with a flap 8 which, by means of suitable fasteners 9, removably retains the carbon sheet 6. Further, an additional flap 10 may be provided with fasteners 11 which removably receive .the main base l or else the base of` the block of sheets if separate from the main base. In this manner substitution of either a new set of leaves, or a new carbon leaf may be accomplished, although it has been found satisfactory to permanently attach the carbon sheet at its right hand .edge with reference to the book of leaves.

Referring particularly to Figures 2 and 3, it is to be noted that the bottom leaf 4; of the set-of three leaves is provided with a cutout 12 spaced upwardly from the cutouts or notches 5 and 7. This notch 12 is de- :signed to lpermit the introduction of a pencil point beneath the sheet 4 after the carbon sheet 6 has been turned to the right, as indicated in Figure 3.

In using this device, for example in making out a bill of lading or any other record requiring a plurality of duplicate copies, the

sheets 2 and 3 and writes the original record operator positions the carbon sheet below the y out on the sheet 2. The carbon is a double 4 faced paper and a copy of the record is formed 'upon the under side of the transparent intermediate sheet 3 and also upon the face of the sheet 4. Thereafter, the operator sli s his pencil point into the notch 5 and swings the sheets 2 and 3 to the left,

as shown in Figure 2. I-Ie then slips his pencil point into the notch .7 and swings the carbon sheet 6 to the right. If desired, the sheets 2 and 4 may be made detachable, and the transparent sheet may be kept asa permanent cop although other-arrangement of y the detacha le sheets may be employed.

v It will be seen that a novel form of manifold sheet has been provided which will permit the forming of a plurality of copies simultaneously by using merely one carbon, which permits the handling of the sheets solely by the out soiling his ands, and which permits the repositioning of the carbon and the new sheets merely by the use of his pencil without in any way requiring him to handle either the carbon or the other sheets with his hands.

It is to be noted that it may be, desired to form only one copy. In this case, the transparent sheet 3 is omitted and the carbon sheet 6 is equipped with its copy material only on encil of the operator withits under side. Obviously, other combinations of sheets-might be employed than that specically set forth herewith without departing from the spirit ofthis invention,

rovided, however, that the notches be ormed, as described either in the identical places detailed in this description or else at places permitting the outlined operation upon the sheets by the use of a pencil.

Although the invention has been described in considerable detail, it is to be understood that the invention may bevariously embodied and is, therefore, to be limited only as claimed.

It is to be distinctly understood that while carbon has been shown and described that lobviously a plurality of carbons may be employed if desired, either simultaneously or else certain of the carbons may be positioned at the bottom of the sheets for future use.

It is to be further understood that the term notch or a similar expression used in the claim is to 'be directed as covering any form of out away portion whatsoever.

I claim:

A manifold ldevice comprising a. base, a block of sheets attached to the base and bound along one side edge, the sheets being arranged in groups of three consisting of a top sheet, a transparent sheet, and a bottom sheet, the top and transparent sheets having registered corners eut away adjacent their free edges, and the bottom sheet being provided with a cutout in itsfree edge spaced upwardly from the cutaway corners of the first mentioned sheets, a roup of carbon sheets secured along an edge opposite the bound edge of the block of sheets, each bein cut out at the corner adjacent its secure edge and adapted to be folded between the transparent and bottom sheets of the group of three to expose a strip of carbon between its cutout portion and the cutaway-corners of the top sheets of the group, whereby a pointer may be used to progressively swing the first two sheets outwardly from their bound edges and thereafter swing the carbon sheet 1n the opposite direction and iinal- 1y swing the third sheet of the group outwardly 1n the same direction as the first mentioned two sheets.

In testimony that I claim the foregoing 'pI have hereunto set my hand at Milwaukee in the county of Milwaukee and State ot Wisconsin.
